he lines Audubon Society 
was organized in 1897 for the study and protection of bird life. 
The Society disseminates facts relating to the importance of 
bird life and strives to increase interest in forest preserves, 
state parks, wild life refuges, and every movement concerned 
with the enforcement of State and Federal laws relative to 
birds. You are earnestly invited to join us in the work which 
demands the most thoughtful efforts of our people.
